First Claim
Patent Images
1. A method for forming a coating on a medical device comprising:
- providing a coating composition comprising a polymer and a solvent of the polymer,applying the coating composition onto the medical device,inducing phase inversion in the coating composition by the addition of a non-solvent of the polymer to the composition, andcausing the coating composition to form a layer of coating on the medical device,wherein the coating has a controlled morphology for controlling the release of an agent and/or a drug from the coating;
wherein the polymer comprises a poly(ester amide) polymer; and
wherein the poly(ester amide) polymer is PEA-TEMPO, PEA-Benzyl, a poly(ester amide) polymer of 0.5 L-Leucine (cyclohexanediol) 0.5 L-Leucine (hexanediol) sebacinate and/or a poly(ester amide) polymer of L-Phenyl Alanine (propanediol) sebacinate.
